Pouch case for secondary battery, secondary battery having same, secondary battery module, and method of manufacturing secondary battery

A pouch case for a secondary battery, the pouch case comprising:

• a forming portion having a predetermined depth, and allowing each of a first end surface and a second end surface of an electrode assembly to be received therein;
• a notch portion spaced apart from each of opposite ends of the forming portion;
• and
• a storing portion covering a portion of the electrode assembly that is not received in the forming portion,
• wherein the forming portion comprises:
• a first forming portion allowing the first end surface of the electrode assembly to be received therein;
• and a second forming portion allowing the second end surface of the electrode assembly to be received therein.

A secondary battery, comprising:

• an electrode assembly;
• and
• a pouch case receiving the electrode assembly therein,
• wherein the pouch case comprises:
• a forming portion having a predetermined depth, and including a first forming portion allowing a first end surface of the electrode assembly to be received therein and a second forming portion allowing a second end surface of the electrode assembly to be received therein;
• a notch portion extending from each of opposite ends of the forming portion or spaced apart from each of the opposite ends of the forming portion;
• and
• a storing portion covering a portion of the electrode assembly that is not received in the forming portion.

A secondary battery module, comprising:

• at least two secondary batteries stacked in a first side surface direction,
• wherein the secondary batteries are arranged to be spaced apart from each other at a predetermined interval, and
• each of the secondary batteries comprises:
• an electrode assembly;
• and
• a pouch case receiving the electrode assembly therein,
• wherein the pouch case comprises:
